Description

Technical Field

[0001] The present invention relates to the field of pipeline dredging, and in particular to a pipeline dredging and desilting robot. Background Art

[0002] Pipeline desilting refers to clearing the pipeline, cleaning the silt and other waste inside the pipeline, and keeping it unobstructed for a long time to prevent urban waterlogging. If the pipeline is not desilted regularly, it will cause sewage overflow, pollute the environment, and cause trouble to people's lives.

[0003] A pipeline clearing robot is disclosed in the patent with publication number CN105156836B, including a main body, a first annular mounting frame and a second annular mounting frame, a blade and a blade gear motor, a drill and a drill gear motor, six high-pressure water cylinders and six driving gear motors, and twelve walking wheels.

[0004] However, the above-mentioned robot still has certain defects when in use. In the prior art, sludge often sticks to the surface of the pipeline. If it is not cleaned, the sludge will accumulate in the pipeline more and more, causing the inside of the pipeline to be easily blocked again. Secondly, the drill bit of the above-mentioned robot is rigidly installed. When unblocking a pipeline that has not been used for a long time, the sludge blocking the pipeline becomes hard and dry due to the dryness inside. During the robot's forward movement, the drill bit will directly hit the hard sludge, which may easily cause the drill bit to tilt, thereby causing the robot's moving direction to shift. If the drill bit contacts the inner wall of the pipeline, there is a risk of damaging the pipeline. Summary of the invention

[0031] In a specific implementation, the heat dissipation ring groove 29 is provided to dissipate heat for the drive motor 30. When the drive motor 30 is cleaning the pipeline, since the inside of the pipeline is humid, in order to avoid a short circuit of the drive motor 30, the drive motor 30 is usually embedded. This will cause certain defects in the heat dissipation of the drive motor 30. The heat dissipation ring groove 29 can be effectively solved.

[0032] As a further implementation scheme of the present invention, an embedded annular groove is opened inside the end of the shell 1 away from the rotating head 2, and an activated carbon adsorbent 19 is embedded inside the embedded annular groove. The side of the embedded annular groove away from the rotating head 2 is connected to multiple air inlet holes, and an electromagnetic valve 14 is arranged in the air inlet hole. The end of the embedded annular groove away from the air inlet hole is connected to a built-in tube 18, and the end of the built-in tube 18 away from the embedded annular groove is connected to an electromagnetic three-way valve 32.

[0035] In specific implementation, Figure 5 As shown, a camera can be further provided at the end of the housing 1 to facilitate observation of the situation inside the pipe. The camera is arranged below the top exhaust hole 42 so that the exhaust hole 42 can form an airflow barrier above the camera when exhausting air, which is helpful to prevent mud and dust inside the pipe from falling on the camera. When using the camera, the rotating head 2 can be rotated until the camera is located between the two sliding plates 5 so that the sliding plates 5 will not obstruct the camera's line of sight.

[0039] In a specific implementation, one end of the collecting pipe 21 away from the U-shaped pipe 12 is connected to a mud pump, and the water supply pipe 11, the collecting pipe 21 and the air supply pipe 13 are all provided with pipe reels, which are similar to the fire hose reels in the prior art, and are used to store water pipes without obstructing the water flow inside the water pipes. This technology is a prior art and will not be disclosed in detail here.

[0040] After the water in the water tank 20 is used up, water can be replenished into the water tank 20 through the water replenishment pipe 11 .

[0041] As a further embodiment of the present invention, a plurality of fixing columns are fixedly connected to the outer side of the housing 1, and lifting frames 9 are rotatably mounted on both ends of the fixing columns. The lifting frame 9 is rotatably connected to a wheel 10 at one end away from the fixing columns.

[0042] In a specific implementation, the lifting frame 9 specifically includes two first columns rotatably connected to both sides of the wheel 10, one end of the two first columns away from the wheel 10 is rotatably connected to the end of the fixed column, a fixed shaft is fixedly connected at the middle section of the two first columns, a groove is provided inside the fixed column, a mounting shaft is rotatably connected inside the groove, the mounting shaft is rotatably connected in the groove, an electric telescopic rod is fixedly connected to the mounting shaft, the fixed end of the electric telescopic rod is fixedly connected to the mounting shaft, and the end of the telescopic end of the electric telescopic rod is rotatably sleeved on the outside of the fixed shaft. The rotation angle of the first column is controlled by controlling the extension and contraction of the electric telescopic rod, so that the wheel 10 is in contact with the inner wall of the pipe. It should be noted that the wheel 10 is made of rubber.

[0043] Working principle of the present invention: When the present invention is used, first, the device is placed in the pipeline to be dredged, and then the lifting frame 9 is controlled to drive the wheel 10 to move outward, so that the wheel 10 abuts against the inner wall of the pipeline, and then the wheel 10 can drive the device to move, so that the device can effectively dredge and desilt the pipeline. It should be noted that in the process of placing the device into the pipeline, the mud pumping head 15 is kept at the lower part of the inside of the pipeline.

[0044] After the device is placed in the pipeline, the wheel 10 is used to drive the device to move to the blocked part of the pipeline, and then the water pump 16 and the drive motor 30 are turned on. After being turned on, the water pump 16 will draw water from the water tank 20 through the rubber hose 17, and then transport the water to the heat dissipation ring groove 29 through the output pipe 31. Through the setting of the heat dissipation ring groove 29, after the water flows into the heat dissipation ring groove 29, it will take away the heat generated by the drive motor 30 due to work, thereby playing a role in cooling the drive motor 30. Cooling the drive motor 30 through the flow of water can effectively prevent the drive motor 30 from being damaged due to overheating.

[0045] After the water flows into the heat dissipation ring groove 29, it will enter the third ring groove 28 through the L-shaped pipe, and then enter the rectangular groove 26 through the output ring groove and the connecting hole. After the water flows into the rectangular groove 26, the water pressure in the rectangular groove 26 increases. Before the water pressure increases to the preset pressure relief value of the pressure relief valve and the preset pressure value of the pressure valve, the water pressure will push the crushing cone head 4 to move away from the rotating head 2 through the rectangular column 38. The water flows into the sliding chamber through the drainage hole 35 and also pushes the sliding plate 5 to move away from the rotating head 2. , so that the brush plate 6 located at the end of the sliding plate 5 can fully abut against the inner wall of the pipe. In order to avoid excessive force exerted by the brush plate 6 on the inner wall of the pipe, by setting the preset pressure relief value of the pressure relief valve, when the water pressure in the rectangular groove 26 is higher than the preset pressure relief value of the pressure relief valve, the pressure relief valve opens, so that the water flow can pass through the sliding chamber into the hollow groove 34, and finally flush around the brush plate 6 through the flushing hole, and then the water flow will be sprayed on the inner wall of the pipe. Through the spraying of the water flow, the brush plate 6 can further realize the cleaning work of the inner wall of the pipe.

[0046] When the water pressure in the rectangular groove 26 is higher than the preset pressure value of the pressure valve, the pressure valve opens, and then allows the water flow to be sprayed onto the inner wall of the pipe through the water outlet 37. On the one hand, it can pre-wet the position of the brush plate 6 that has not been cleaned, so that the brush plate 6 can effectively clean the sludge that is adhered to the inner wall of the pipe due to drying. On the other hand, it can also flush down part of the sludge adhered to the inner wall of the pipe, so that the brush plate 6 only needs to clean the remaining sludge. By cleaning both sides of the inner wall of the pipe, the inner wall of the pipe can be cleaned more thoroughly.

[0047] After the driving motor 30 is turned on, it will drive the rotating head 2 to rotate through the rotating shaft 27, and then drive the sliding plate 5 and the brush plate 6 to rotate effectively through the rotating head 2. During the rotation of the brush plate 6, the centrifugal force generated by the rotation of the rotating head 2 will make the brush plate 6 more fully contact with the inner wall of the pipe, so that the brush plate 6 can further clean the inner wall of the pipe to avoid stubborn dirt from adhering to the inner wall of the pipe. At the same time, the full contact between the brush plate 6 and the inner wall of the pipe can also have a certain polishing effect on the pipe, making the inner wall of the pipe smoother, which is conducive to avoiding dirt from adhering to the inner wall of the pipe again, and the time for dirt to appear on the inner wall of the pipe can be delayed, thereby delaying the timeline for the next pipeline dredging and reducing the workload of the staff.

[0048] During the rotation of the rotating head 2, through the arrangement of the rectangular groove 26 and the rectangular column 38, the rotating head 2 can also drive the crushing cone head 4 to rotate effectively. During the rotation of the crushing cone head 4, the spiral plate 36 can also be driven to rotate. When the spiral plate 36 rotates, if the front of the device is blocked by sludge, the spiral plate 36 can be used to effectively clear it.

[0049] When clearing and cleaning a pipe that has been in a dry state for a long time, the sludge inside it will coagulate, which will make the sludge harder on the one hand and make the inner wall of the pipe more difficult to clean on the other hand. If the sludge completely blocks the inside of the pipe, the crushing cone head 4 will be needed to gradually clear the pipe. When the crushing cone head 4 makes initial contact with the hard sludge, due to the forward power of the wheel 10, the crushing cone head 4 directly hits the sludge, so there is a possibility that the device may tilt. When the device tilts to the point where the crushing cone head 4 contacts the inner wall of the pipe, there is a risk that the crushing cone head 4 will break the pipe.

[0050] By setting the pressure component, when the crushing cone head 4 contacts the hard sludge or hard debris in the pipeline, the crushing cone head 4 is subjected to resistance, which will act on the water inside the rectangular groove 26 in the reverse direction. After the water is squeezed, the water pressure will be further increased, so that the water flow will be discharged through the flushing hole and the water outlet 37 with greater force, which is conducive to further flushing the sludge with strong water pressure. At the same time, it can also increase the amount of water used to flush the hard sludge, so that the hard sludge in contact with the crushing cone head 4 becomes moist, which can facilitate the crushing cone head 4 to effectively dredge the blocked pipeline. When the water pressure inside the rectangular groove 26 increases, the pressure applied by the water pressure to the brush plate 6 through the sliding plate 5 will also increase, so that the brush plate 6 will further abut against the inner wall of the pipeline, thereby reinforcing the device, so that the device can stabilize its shape under the abutment of the brush plate 6 and maintain the direction of travel of the device, which is conducive to avoiding the situation where the crushing cone head 4 contacts the inner wall of the pipeline due to the tilt of the device.

[0051] In the process of clearing the pipeline, through the setting of the mud pumping head 15, the telescopic tube can extend the mud pumping head 15, so that the mud pumping head 15 can abut against the inner bottom wall of the pipeline, and then the collecting pipe 21 can extract the sludge through the U-shaped tube 12 and the built-in empty groove 22. At the same time, by spraying water on the inner wall of the pipeline, the sludge can be made more moist, which is convenient for the sludge to be extracted along with the water flow.

[0052] When the driving motor 30 is turned on, the air pump 23 is also turned on. After the air pump 23 is turned on, air will be extracted through the electromagnetic three-way valve 32, and then the air will be transported to the first annular groove 24. After the gas enters the first annular groove 24, part of the gas will be discharged through the exhaust hole 42, and the other part of the gas will enter the transverse groove through the second annular groove 25 and the connecting air pipe 33. The gas discharged through the exhaust hole 42 will be blown to the end of the outer shell 1 close to the rotating head 2, and the gas will be blown to the outside of the rotating head 2, which is conducive to blowing off the dust and impurities located in front of the rotating head 2. At the same time, it can also make the water discharged through the water outlet 37 diffuse toward the direction of the rotating head 2 away from the side of the outer shell 1, so as to sprinkle water and moisten the pipe to be cleaned in front in advance, which is conducive to improving the wetting efficiency of the device on the inner wall of the pipe.

[0053] The gas entering the transverse groove will be blown onto the inner wall of the pipe through the buffer chamber 40 and the air outlet 7, which is helpful to blow off the sludge impurities brushed off by the brush plate 6 and prevent the sludge impurities from being unable to fall effectively under the action of gravity.

[0054] Through the setting of the electromagnetic three-way valve 32, when the dry pipeline is dredged, the input end of the air pump 23 is connected to the built-in tube 18 through the electromagnetic three-way valve 32. When the air pump 23 is turned on, air will be drawn through the built-in tube 18, and the built-in tube 18 will draw air from the tail of the device through the activated carbon adsorbent 19 and the electromagnetic valve 14. In this process, the activated carbon adsorbent 19 can adsorb some toxic gases in the gas inside the pipeline, and can also adsorb the odor inside the pipeline to a certain extent, which is beneficial to improve the air quality inside the pipeline and reduce the probability of breeding germs and bacteria inside the pipeline. When clearing a wet or water-filled pipe, close the solenoid valve 14, and at the same time control the solenoid three-way valve 32 to connect the air supply pipe 13 with the input end of the air pump 23, so that the air pump 23 can draw air from the outside. Through the circulation of airflow, when clearing a water-filled pipe, the airflow can also be used to cause the flow of water in the pipe, and then the flow of water can be used to flush the sludge in the pipe, so that the sludge can become looser, making it easier for the brush plate 6 to clean the pipe.
